Description
Technical field
The present invention relates to fire-resistant polyamide composite.
Background technology
All the time, as the material that constitutes electronic unit, use heating and melting and can be shaped to the polyamide resin of regulation shape.Usually, as widely used polymeric amide, can enumerate nylon 6, nylon 66 etc.This fatty polyamide has good formability, and on the other hand, and the raw material as being used to make the surface mounting assembly that is exposed to junctor of resembling under the such hot conditions of reflow soldering operation and so on does not possess enough thermotolerances.
Based on this background,, developed nylon 46 as polymeric amide with high heat resistance.But nylon 46 exists the high problem of water-absorbent, uses the electrical and electronic parts of nylon 46 resin combination moulding to have situation about changing because of the suction size.If formed body suction then because bubbling can appear in the heating in the reflow soldering operation, problem such as promptly expands.Particularly in recent years, consider, progressively adopting the surface mounting mode of using lead-free solder from the viewpoint of environmental problem.Lead-free solder than in the past lead solder fusing point height arranged, therefore temperature being installed must be higher 10～20 ℃ than in the past.Therefore the use of nylon 46 becomes more and more difficult.
At this situation, developed by aromatic dicarboxylic acid and aliphatics Alkylenediamine deutero-aromatic polyamides such as terephthalic acids.Compare with fatty polyamides such as nylon 46s, aromatic polyamide has thermotolerance, the more excellent feature of low water absorbable.In addition, compare with nylon 46, aromatic polyamide can have high rigidity, does not have sufficient flexible problem sometimes but exist.Especially, if the toughness of the connector material of thin-walled thin space junctor purposes is insufficient, when then terminal is pressed into and when operation plug, phenomenons such as goods break, albefaction can appear.Therefore, the exploitation that waits in expectation has a more material of high tenacity.
If increase the ratio of polyamide resin, reduce flame retardant amount, then flexible improves becomes possibility.But,, usually, often require such high flame retardant and the resistivity against fire of stipulating among AIA's laboratory standard (Underwriters Laboratories Standard) UL94 of V-0 for electronic units such as junctors.Therefore, need under the situation of not damaging flame retardant resistance, also have the material of high tenacity.
On the other hand, as existing fire retardant, use halogen-containing fire retardants such as brominated polyphenylether, brominated Polystyrene, brominated polystyrene usually.But,, can be accompanied by the generation of toxic gas hydrogen halide during burning with regard to halogen compounds.Become at global warming under the situation of problem, exploitation thermotolerance height, not halogen-containing fire retardant are important.As this fire retardant, people are paying close attention to the utilization (referring to patent documentation 1～5) of phosphinates.
